RAILWAY-CROSSING.

SPECIFICATION forming part of Letters Patent No. 530,197, dated December4, 1894.

I Application filed March 30, 1894. Serial No. 505,768. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR J. MOXHAM, a subject of the Queen of GreatBritain, residing at Johnstown, county of Gambria, State ofPennsylvania, have invented a new and useful Improvement inRailway-Crossings, of which the following specification is a true andexact description, due reference being had to the accompanying drawings.

My invention, Case 40, relates to those structures used where onerailroad track crosses another track, whether both be steam roads, orone a street railroad. In these crossings, owing to the weight and speedof the trains on the steam' road, it is exceedingly difficult toconstruct a crossing which will stand the wear and tear for any lengthof time.

The object of my invention is to provide a crossing which will carry thecars across the other track with little jar, and which is at thesametime well adapted to withstand the wear put upon it by the travel uponthe rails. It is difficult in a crossing of this kind, constructed ofvarious pieces of rail fitted and bolted together, to keep the boltstight and the structure rigid, as the jar of the trains soon workseverything loose and greatly destroys the efficiency of the crossing.

By my invention I am enabled to form a crossing without bolts or similarfastenings and which is in one integral piece and consequently cannotbecome loose.

Referring to the drawings: Figure 1,shows a top view of a crossingembodying my inven tion and adapted for use Where a street car trackcrosses a steam road. Fig. 2 is a section on XX of the street track inFig.1. Fig. 3 is a section on Y-Y of the steam track. Fig. at is a sideView of a portion of the street track illustrating a detail hereinafterdescribed. Fig.-5 is a section on line ZZ of Fig. 4. Fig. 6 is a detailhereinafter explained. Fig. 7 is a plan of crossing adapted for usewhere one steam road crosses another.

In general my invention consists in forming the rails-upon which thesteam cars travel of substantially heavier section than the usual railsof the steam track, and having other advantages which I will point out.In constructing the crossing I first form two of these steam-track railscontinuous through the crossing and weld the crossing rails to them, andthus join the crossing in one integral structure with no bolts to loosenor loose pieces to become displaced.

In the drawings, A are the rails of a street-- car track, and B, therails of a steam track. The heads of the various rails are marked H, andthe grooves in which the flanges of the car wheels run are marked G.

In constructing the crossing I form the steam rail B as follows: I takea bar of rolled steel of the configuration shown in full lines in Fig.6, or I plane a rectangular billet, as shown by the dotted lines, downto the shape of the full lines. This shape. it is seen, is substantiallyrectangular and is provided with base flanges for spiking down to theties, and a groove for the wheel flange. The head of this section issubstantially wider than the head of an ordinary rail, say four or five.

inches. The ends of this bar I reduce to conform to the shape of theadjoining rails, as shown at-G. This may be done by planing or milling.In Fig. 1 the ends arethe shape of the abutting rail for some distancefrom the end; but in Fig. 7 they are tapered ofi'on the outsideand thesplice bar bent to correspond. This removes any weakness which might bein the rail where the reduced section joins the full section. Thatportion of the widened head which lies outside of the street track Itaper off or incline, as shown at D. The object of this is-t-hat a carwheel, the tread of which is worn hollow near the flange and whichconsequently hangs below the top of the rail on the outside, may belifted up upon the widened rail head gradually, and then carried overthe crossing rail without the blow and jump which would result from theoverhanging portion of the wheel striking it.

In crossings as usually constructed it is customary to place a separaterail, or other bearing surface to perform this lifting of the wheel,close against the outside of the head of the steam rail. This separatepiece becomes loose and is with difficulty retained in position. Thesteam rail for one track being thus formed, I weld to it the crossingtrack rails A and E by electric welding, or otherwise, if desired. Toreinforce the welded points and strengthen the crossing in the caseswhere one of the tracks is a street car track and the street rails areof small section I prepare the ends of the street track rails beforewelding by putting theininto a mold and casting molten steel around theends, as shown in Figs. 4 and 5. This practically makes the end of therail rectangular and affords a much larger welding area than would bethe case if the rail alone were welded. The welding of the enlarged endto the steam rail serves also to weld the cast steel portion to thestreet car rail at the point of weld, thus reinforcing the connection ofthe cast steel to the street rail. Where all the rails are of the heavysection this reinforcement is not necessary. After the rails are weldedtogether the grooves for the flanges of the car wheels are planedthrough the rails B at F. Th us I form a crossing in which the carwheels have only the gap left for the flange of the crossing wheel andexcept for this point is supported throughout by the tread. The steamroad is provided with a rail of increased width of head and without anyportions which may become loose.

Having thus described myinvention, what I claim, and desire to protectby Letters Patent, is-

1. In a railroad crossing a rail one portion of which is provided with aguard and a head widened 0n the outside while the end portions areadapted to mate with the abutting track rails.

2. In a railroad crossing a rail the central portion of which isprovided with a head wider than the end portions, the ends of saidwidened portions beinginclined as described.

3. In a railroad crossing a rail having in the central portion the headwidened as described, the ends of said widened portion being inclined,said rail having the abutting rails of the crossing track unitedthereto.

4. In a railroad crossing a rail the central portion of which is devoidof web and is provided with a head wider than the abutting track rails,a longitudinal groove adjacent to the gage line of the head for thewheel flange, and a guard forming one wall of the groove, the ends ofsaid rail being provided with a web and base flanges.

5. In a railroad crossing a rail separately constructed, the end ofwhich is reinforced by cast metal secured thereto, the whole beingintegrally united to an abutting rail.

6. In a-railroad crossing a rail the central portion of which is ofsubstantially rectangular form and provided with flanges for securing tothe tie, and a longitudinal groove for the wheel flange, while the endportions are provided with a web and base flanges.

7. An integral railroad crossing composed of rails having portions oftheir heads widened on the outside for the purpose set forth; inclinesat the end of said widened portions, and end portions mating with theadjoining track rails.

8. A rail, the central portion of which is provided with a head ofgreater width than the end portions of said rail said end portions beingprovided with a web and base flanges.

9. A rail, the central portion of which is provided with a head ofgreater width than the end portions, the ends of said widened portionsbeing inclined.

10. A rail, the central portion of which is provided with a head ofgreater width than the end portions, the ends of said widened portionbeing inclined and tapered inward to the width of head at end portionsof the rail.

11. A rail, the central portion of which is substantially rectangular inform and provided with flanges for securing to the tie, and alongitudinal groove for the wheel flange, the end portions beingprovided with a web and base flanges.

12. A rail, the central portion of which is substantially rectangular inform and provided with flanges for securing to the tie, and alongitudinal groove for the wheel flange, the end portions beingprovided with a web and base flanges, and the central portion beingprovided with a head of greater width than the end portions, the ends ofsaid central portion being inclined.

In testimony whereof I have affixed my signature in presence of twowitnesses.

ARTHUR J. MOXIIAM.
